动态模拟法在山口电站增效扩容改造机组选型中的应用

Application of Dynamic Simulation Method in Unit Selection of Shankou Power Plant s Efficiency-increasing and Capacity-expanding Transformation

对于性能相近的水轮机选型,传统的选型比较方法难以区分优劣,为较好解决性能相近的机组选型问题,以山口水电站为例证,采用动态模拟法,即通过设定技术经济目标参量Y=(y 1,y 2,…,y n)和包含机组特征参数的决策变量X=(x 1,x 2,…,x n),将不同的X与客观的水文过程匹配,通过智能算法寻优,当取得opt Y=Y*时,其最优解X*对应的机组为所选机组,该方法对类似工程有借鉴和参考作用。

Unit selection is the key step in the process of hydropower station efficiency and capacity expansion,and its impact on the economic benefits after the transformation is fundamental.For hydraulic turbines with similar performance,the traditional selection and comparison method is difficult to distinguish between advantages and disadvantages.In order to better solve the problem of selection of hydraulic turbine units with similar performance,this paper adopts the dynamic simulation method,that is,by setting the technical and economic target parameter and the decision variable containing the unit characteristic parameter,the different is matched with the objective hydrological process,and the intelligent algorithm is used to optimize.When is obtained,the unit corresponding to the optimal solution is the selected unit.Taking Shankou hydropower station as an example,the superiority of dynamic simulation method is illustrated.This method can be used for reference in similar projects.
